If you ’ve ever thought that cooking and gardening have a few things in common – mainly using “ ingredients ” and come after a “ recipe ” to make something out of nothing – you ’re going to wish this clause in which I explicate how to make a give bulb lasagna .
What do pasta , cheese and sauce have to do with planting bulbs ?
One word : layering .
Planting lasagna - style have-to doe with to layering your bulb in flush pots to optimize the use of space and to extend the blooming period of that container . This superimposed planting method allows gardeners to mix lightbulb in a kind of colour , sizes and blooming times to make a showstopping garden video display .

How many bulbs do I need for lasagna planting?
That depend on the size of your hatful , the size of it of the electric-light bulb and how compact ( or crowd ) you want your arrangement to be . Just to give you an idea , I ’m plant in a container that ’s about 12 inch tall ( roughly 30 centimetre ) and 14 in in diameter ( about 35 cm ) at the top rim . I ’ve ended up plant 46 bulb in total . It may seem like a mess for a mid - sized pot , but I retrieve they look much better in bloom when they ’re generously planted .
What I wish to do is collect all the bulbs I want to let in in my display , keep them divided by type , then see how many of each case I can fit in the mountain without overcrowding . The bulb that are left over will end up in my garden beds .
As a ecumenical prescript of thumb , you ’ll need few large medulla , slightly more mid - sized bulbs and importantly more small bulbs . This accounts not only for the size of the bulbs , but also for how your potting container taper down .
Here’s the recipe for planting a lasagna bulb container:
Step 1: Prepare the pot.
If you ’re planning on planting at least three layer of bulb , ensure you start with a pot that can accommodate all this wad . Always choose a container that has enough drainage hole because waterlogging will lead to bulb putrefaction . likewise , choose compost or potting soil that ’s designed for outdoors use .
If you ’re not indisputable whether your potting grunge will drain well , you may set out by summate a layer of LECA , terracotta shards , horticultural gravel , pebbles , sea shells or twig at the bottom of the pot . The purpose of this supererogatory layer is to allow the urine to drain quickly and prevent the potbelly from becoming waterlogged over the wet wintertime months .
The slew that I ’m using to establish my lasagna bulbs will be left outdoors all winter foresighted , so I ’m add together a bed of LECA ( expanded the Great Compromiser pebbles ) to the bottom of the container to foreclose it from retaining too much moisture .
Step 2: Add the first layer of compost.
The first layer of compost should be thick enough to allow for proper radical evolution for the first stratum of bulb . Depending on the sizing of your pot , aim to occupy a quarter to a third of the lot at this percentage point . call up that all the bulbs will develop their root downwards , so they ’ll all ultimately practice this layer as a base .
Step 3: Add the first layer of bulbs, then add some compost.
The first level of bulbs will be your large light bulb that bloom subsequently . In my case , I ’m mixing a few people of colour of constitutive hyacinths from the ‘ Pearl ’ cultivar ( ‘ pinkish Pearl ’ , ‘ White Pearl ’ and ‘ Blue Pearl ’ ) .
for get a full , compact video display , I plant them at a aloofness of about one bulb ’s width , or even tight . This still allows the bulbs some way to plump up when watered , shift and even separate , while they ’re also tightlipped enough to create a rich showing . Remember to always plant your bulbswith the pointy side up .
Top up this bed of medulla oblongata with a layer of compost of about 3 or 4 inches , depending on how tall your mass is . consider of the potting soil as the lasagna “ sauce ” that helps to keep the layers congealed together .
A few bulbs that are suitable for a first layer admit hyacinths , Allium andlate - spring tulips .
Step 4: Add the middle layer of bulbs, then add more compost.
For the mediate stratum , you should pick out bulbs that are mid - season bloomers . I ’m constitute a commixture of Narcissus pseudonarcissus ( Narcissus ‘ Dutch Master ’ ) and tulips ( Tulipa ‘ Grand Perfection ’ ) . Again , do n’t be afraid to pile them in .
I admit , it does reckon weird to plant them on top of each other . But eternal sleep assured that , once the bottom bulbs start germinate , the growth will sheer off course and go around the bulbs on top if they encounter resistance . Having incandescent lamp stack on top of one another will not stunt the bottom ones ’ growth .
For the middle layer , the sky is the bound – you could choose from one C of cultivar ofmid - time of year tulipsand mid - time of year daffodils . Some hyacinth that flower in mid - bounce are also good prospect for this level .
Once all your mid - layer bulb are in topographic point , add together a generous percentage of compost on top of them and level it off .
Step 5: Add the early spring bulbs, then add compost
The last level of light bulb that you ’re plant , but the first stratum if you ’re count from the top , are the bulbs that blossom in late wintertime and former spring . They ’ll be the first to treat you with their foliage and colors while the electric-light bulb underneath take their time to sprout .
For the top layer , you may select different cultivar of Anemone quinquefolia , crocus , muscari or miniature flag ( Iris reticulata ) . For my arrangement , I ’m planting a commixture of white , pink and blue Spanish bluebells ( Hyacinthoides hispanica ) . If my calculation are correct , and the weather cooperates , the first and second layer bulbs should be in peak at the same time .
Finish off the mixture by adding the top layer of compost . recall that it ’s best not to immerse the modest bulbs too deep , certainly not deeper than three times their height ; so if you have too much surplus space at the top , do n’t be tempted to pack it in with dirt .
Step 6: Water the pot thoroughly.
Hopefully , you ’ve been keep the bulbs dry while they were in storage . Now ’s the meter to break that ironical while by give them a thorough watering . I used to think that the dampness of the clean compost was enough , but that does n’t even get down to comprehend it . Bulbs take to be save moist ( but not waterlogged ) so as to encourage root word formation right after planting . And the strong the rootage from the get - go , the more vigorous the bloom .
If you ’re plan on leave the potentiometer outdoors in the ingredient , you should monitor the soil moisture and keep watering the bulbs if you ’re not getting enough pelting . A lack of water during this ontogeny period will often result in spindly weak rosiness derive spring .
Step 7: Add a layer of mulch.
Around these parts , no good planting session end without a level of mulch . The same enforce whether I ’m planting perennial , annuals or bulb . When you plant in containers , mulch serves several purposes – it slows down soil compaction in case of heavy pelting ; it keeps the temperature of the filth pretty even , and it forestall little critters from smelling freshly scratched grunge and digging in to snack on the bulbs .
Think of mulch as a protective layer of insulation during the cold month . It does n’t have to be fancy or expensive . In the fall , a dense bed of juiceless leaves is my mulch of choice . It ’s free ; it ’s clean-living and it ’s easy to get even in my suburban neighborhood ( minus the stares of my neighbour , but luckily they never question the motives of a nurseryman ) .
When should I plant my lasagna bulb pot?
To get the good outcome , you should implant your bulbs in the fall or very early winter . That means anywhere between October and December , as long as the temperature has n’t souse below freezing . If you imbed it too early in the fall , when the temperature is still warm , you risk the chance of your bulbs sprouting untimely . It ’s good to hold back than to jump the gun when it comes to implant your bulbs .
I held off for as long as I could because we ’ve been having a affectionate spill . So some of the hyacinth bulbs were quite active ( splitting and rise rootage ) at the time of planting .
Can I keep my spring bulb container outside?
Yes , you could keep your lasagna bulb container outdoors . It ’s better if you may post the pot in a sheltered location , rather than out in the outdoors in the centre of your grand . The goal is to keep it sheltered from wind and frost , so somewhere along a ardent wall would be ideal . If you pick out to place it under shelter , remember to keep watering it . Keep in mind that bulbs need a period of cold-blooded ( about six weeks or so ) to offend dormancy , so do n’t store them in a smirch that get too warm in the winter , such as a heated nursery or garage .
If you get multiple consecutive 24-hour interval when the temperature falls way below freezing , you could protect the sens with a blanket , a felt cover or a layer of bubble wrapper .
On the other hand , if you get really cockeyed winters with a lot of precipitation , it ’s a skilful musical theme to call forth your pot on a yoke of brick or pieces of wood . The intention of these stilts is to open up the drainage mess so as to allow the rainwater to debilitate through and not make a pool at the bottom of the pot . Yes , this can pass even if you ’ve tote up a layer of gritty material at the bottom .
Finally , once the weather start to warm up in outflow , you’re able to glower your good deal back down in their saucers and check that they do n’t dry out too much .
What bulbs can I mix in a lasagna-style arrangement?
This is the fun part , is n’t it ? This is where you get to let your vision take the steer . There ’s no strict dominion about medulla mix . Keep in mind that with bulb such as tulips and Narcissus pseudonarcissus , there are century of cultivars that span the blooming season .
So you could just make a tulip bulb lasagna by layer late - time of year tulips ( you ’ll find these in the Parrot , undivided late and Double late mathematical group ) followed by mid - time of year ones ( such as Darwin Hybrid , Triumph and Fringed tulip ) and topped up with early flower tulip ( in general from the Fosteriana , Greigii , Kaufmanniana , Single other and bivalent early mathematical group ) . You ’ll line up the flower meter information on the site of the trafficker and on the medulla oblongata packaging . Orrefer to our usher to the different type of tulips and their blooming full point .
Trying to time the flower season is also not a very strict rule . The purpose of the lasagna method acting is to extend the blooming meter and enjoy a longer - lasting spring display . But you could also layer bulbs that have the same blooming time , if you ’re contented with a pot with a shorter timeline . The bulbs you localise at the bottom might take a snatch longer to reach the surface , but generally your anthesis time will overlap , creating a luxuriant burst of color .
Another “ pattern ” that you may safely ruin is the one that dictate the number of bed . You do n’t have to stay to the dominion of three . you may plant four or even five layers of bulbs if you ’re using a muckle that ’s tall enough to accommodate all of them .
The one rule you should follow when you choose your bulbs is the one that states you should n’t swallow up little early season bulbs too deeply . So medulla such as crocuses , muscari , wood anemone and species tulips should n’t be put right at the bottom of a deep potty . If you do require an early display , simply mix these small lightbulb in a shallower pot with very well drain .
Ultimately , in my experience , I wish to take the same approach with lasagna bulb planting as I do with my cooking in the declivity : use the formula as my guideline , but deviate just enough to make it interesting and satiate my creative taste buds . And just like with preparation , the more container planting I do , the more confident I get in my tastes and my intuition . The results never fail to delight .
